It can be the field's offset, the field's name, or the field's table dot field name (tablename.fieldname)

$conn = cubrid_connect(localhost, 33113, demodb);
$req = cubrid_execute($conn, SELECT * FROM code);
$result = cubrid_result($req, 0);
var_dump($result);
$result = cubrid_result($req, 0, 1);
var_dump($result);
$result = cubrid_result($req, 5, f_name);
var_dump($result);
//$result = cubrid_result($req, 5, code.f_name);
//var_dump($result);
$result = cubrid_result($req, 5, code.f_name);
var_dump($result);
